Verify Compatibility Before Purchase
Match the exact layout: number of buttons, presence of sunroof control, and connector style.
Confirm whether your cab has manual or automatic ventilation flaps.
Disconnect Battery Before Installation
Prevents short circuits or accidental triggering of systems.
Wait 5 minutes after disconnecting to discharge capacitors.
Handle with Care
Avoid dropping — internal circuit boards can crack.
Do not press buttons forcefully during installation.
Ensure Secure Mounting
Use original screws or clips; loose panels rattle while driving.
Seal around edges if exposed to moisture.
Check All Functions After Installation
Dome light
Reading lamps
Ventilation control
Sunroof (if applicable)
Test each switch:
Look for flickering or delayed response — sign of poor connection.
Avoid Moisture Exposure
If roof lining leaks, repair it before installing a new panel.
Consider adding a protective cover or silicone sealant (non-conductive).
Use Correct Tools
Use plastic pry tools to remove old unit — avoid scratching the headliner.
Never use metal screwdrivers near live connectors.
Label Wiring Harness (If Modified)
Aftermarket versions may have different pinouts — double-check connections.
Do Not Wash with Water
Never immerse the unit in water or clean with wet cloths.
Use dry or slightly damp microfiber cloth only.
Storage Advice
Keep in original packaging until use.
Store in cool, dry place away from direct sunlight and extreme temperatures.
